WordPress:
WordPress is an open-source content management system. It is the easiest and most powerful blogging CMS in existence today.
CageFS:
CageFS is a virtualized file system and it has a set of tools to contain each user in its own ‘cage’. Every customer can have fully functional CageFS with all the system files and tools. It can cage any scripts execution done via SSH, Cron Jobs or any other PAM enabled service.
Steps to resolve the “Missing a temporary folder” in WordPress:
1. Log into WHM.
2. Navigate to Plugins “>>” CageFS.
3. Select the user you need to remove from the CageFS and click on “>>”.
4. Then click on “Update CageFS skeleton”.
Now you disabled CageFS for that particular user. To re-enable the user select the user from “Disabled users” and click on “<<“. Once you’ve done that, click on “Update CageFS skeleton”.
